Description

Building formwork for easy assembly and dismantling

Technical field:

The utility model relates to the technical field of construction equipment, in particular to a construction formwork which is convenient for assembly and disassembly.

Background technique:

Concrete components are a common component in building construction, such as concreted floors, columns, walls, etc. And pouring concrete member needs to use formwork usually, forms the mold cavity of concrete member by formwork, then pours the concrete and other fillers that have stirred in the mold cavity that this formwork forms. After the concrete has solidified, the formwork is removed to obtain the concrete member. The current formwork generally has a complete inner surface, and several formworks are used to form a cavity, which must be fixed to prevent the inner surface from being pressured when the concrete is poured, causing the cavity to collapse or deform. The fixing method is generally fixed on the periphery. , that is, one end of several columns is pressed against the outside of the formwork, and the other end is supported on the ground or other walls to form a fixed structure. This construction method is widely used in the construction field, but it has great shortcomings: first, the assembly and dismantling process of this fixing method is cumbersome, resulting in low construction efficiency; Uneven, easy to damage the formwork; Third, this peripheral fixing method requires a large number of supporting devices, which will inevitably take up a lot of space, waste materials, and easily hinder construction; in addition, traditional building formwork is usually made of wooden materials, and its service life Shorter, it is difficult to reuse many times, resulting in higher product cost, and it needs to consume a certain amount of wood, which is not conducive to environmental protection.

Utility model content:

The purpose of the utility model is to overcome the above-mentioned inadequacies of the product, and provide a building formwork and its fixing structure which is not only stable and compact in structure, but also easy to assemble and dismantle.

The technical solution adopted by the utility model to achieve its purpose is: the building formwork that is convenient to assemble and dismantle is composed of several plastic formworks, each formwork is provided with several through holes that run through the surface of the formwork, and the formwork is connected by a connecting piece Assembled through the through hole, and a limiting mechanism is provided on the outer part of the template to prevent the template from moving due to the force on the inner surface.

The limiting mechanism can be a sleeve that can be sleeved on the connecting piece, and several threaded through holes are opened on the side of the sleeve, and limiting bolts are connected to the threaded through holes. The connecting piece is a round steel rod, the casing is a round casing, and three threaded holes are opened on the casing, when the limiting bolts are tightened, the casing is tightly fixed on the connecting rod, and the inner end surface of the casing is against the the outer surface of the formwork, thereby preventing the formwork from detaching

Alternatively, both ends of the connector of the present invention are threaded, and nuts are respectively connected to form a limiting mechanism. A gasket is provided between the nut and the outer surface of the formwork to avoid damage to the formwork due to excessive local pressure at the opening of the formwork.

After the utility model adopts the above structure, several templates can be easily combined into the required cavity by using the perforated connection, and the fixed structure is stable during pouring, the shaping effect is good, and the structure is compact, which will not affect other constructions; When dismantling, you only need to loosen the bolts or nuts of the limiting mechanism to take off the formwork, which is simple and quick, and the parts exposed to the pouring components on the connectors can be kept or sawed off for recycling as needed.

Description of drawings:

Fig. 1 is the inside view of template of the present utility model;

Fig. 2 is the outside view of template of the present utility model;

Fig. 3 is the assembly diagram of an embodiment of the utility model;

Fig. 4 is an assembly diagram of another embodiment of the present invention.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, the formwork 1 of the present invention is made of plastic material, the inner side 11 is a flat surface, and the outer surface 12 is formed with a grid 120 . The grid 120 can mainly play the role of saving material and enhancing the overall strength of the formwork 1 . The shape and size of the grid 120 can be designed in different modes according to the actual situation.

The formwork 1 is rectangular as a whole, and there are several through holes 10 penetrating the surface of the formwork 1 on it, and its function is to pass through the connecting piece and connect with another formwork to form the mold cavity required by the building. As shown in Figure 3, the connector is a circular steel rod 2, which crosses two planks 1, and the end of the steel rod 2 of the connector is provided with a limiting mechanism, which is a circular sleeve 3, and the inner diameter of the sleeve 3 is It is slightly larger than the steel rod 2, and the outer diameter of the casing 3 is larger than the diameter of the through hole 10 on the template 1. There are 3 threaded holes on the side of the casing 3 and are respectively connected with limiting bolts 31. In addition, when inserting Before the casing 3, a spacer 4 is inserted, which can better define and protect the formwork. Before it is fixed, the formwork 1 can move within the range of the steel rod 2 of the connecting piece. After the distance is determined, it is only necessary to tighten the limiting bolts 31 so that the inner end is against the steel rod 2 to fix the sleeve 3, thereby limiting When the formwork 1 moves and pours, the formwork 1 is also limited by the casing 3 and the spacer 4, so a mold cavity can be formed to facilitate the completion of pouring.

Of course, as shown in FIG. 4 , the limiting mechanism can also be directly fixed by nuts 5 , that is, screw threads at both ends of the steel rod 2 of the connector, and then fixed by gaskets 4 and nuts 5 .

After the casting component is formed, when removing the template, only need to loosen the limit bolt 31, take off the casing 3 and the gasket 4, or unscrew the nut 5, take out the gasket, and the template 1 can be easily removed. After the formwork 1 is removed, the redundant parts at both ends of the connecting piece steel rod 2 can be kept as required, or can be sawed off directly.

In summary, the utility model has a simple structure, is convenient to install and dismantle, and is beneficial to improving construction efficiency.
